ea'rENr Fri- SIGN ORS T0 DURO METAL PRODUCTS COMPANY, OF CHICAGO,ILLINOIS, A CORPORA- TION OF ILLINOIS' WHEEL rULLEn Application ledFebruary 27, 1931. Serial No. 518,721.

rl"his invention relates to wheel puilers suitable for use in removingautomobile wheels from the axle shafts on which they are mounted, andsimilar purposes.

One ofthe objects of the invention is to provide an improved wheelpuller.

A further object of the invention is to provide a wheel puller which isadapted to apply an even pull around the circumference of the part ofthe wheel upon which it acts.

A further object of the invention is to provide a Wheel puller which maybe easily and expeditiously attached to the wheel.

A further object of the invention is to provide a wheel puller which isadapted to engage the wheel hub and the axle shaft to insure correctalignment, and which may be readily applied thereto.

A further object of the invention is to provide a wheel puller which isparticularly adapted for use in removing automobile Wheels w iose hubsare provided. with a. radially projecting bead or ring. n

Other objects, advantages and capabilities of the invention will readilyappear from the following description of the preferred embodiment, takenin conjunction with the accompanying drawings in which Figure 1 is aneleva tional view of the wheel puller in open condition; and

F ig. 2 is a sectional View through the Wheel puller in operativeposition.

Referring to the drawings, the wheel puller comprises a substantiallycup shaped housing 10 which is constituted by two similar elements 11and 12, which are suitably hinged together, for example by lugs 13,integrally carried by the elements at adj acent longitudinal edges, anda pin 14 which extends through openings therein.

Adjacent their other longitudinal edges the elements 11 and 12 areprovided with lugs 15 and 16 respectively. A bolt 17 is pivotallymounted in the lugs 16 so that it may be swung into position between thelugs 15 when the elements 11 and 12 are Closed. A wing nut 18 and washer19 mounted on the bolt 17 enable the elements of the housing 10 to bereadily secured together 1n operative relation.

At the outer end of the cup shaped housing 10, the elements 11 and 12are provided with an inwardly directed flange or bead 20. Thelongitudinal edges of the elements l1 and 12 which are brought intocontact when the housing is closed, are provided with intermeshing meanswhich maintain Vthe elements in cooperating relation and communicatethrust from one to the other. Thus element 12 is provided with a detent21, while the element 11 is provided with a corresponding recess 22..The edges Aof the detent and recessesadjacent the open end of thehousing 10 are in thecircumferential direction so that thrust may becommunicated from the elementy 11 to the element 12 Without acircumferential component. The edges kofthe detent 21 and recess22remote from the open end of the housing are preferably oblique orcurvedso as to assist'in bringing the elements 11 and 12 into relation whenthe hous-` ingfis closed. o

`rlhe elements 11 and 12 of the housing *10,v carry integral end walls23 and 24C respectively Which form the bottom or base of the cup shapedhousing 10. rllhese end walls are provided With registeringl recesseswhich provide an opening 25 in the base of th 10 when the same isclosed.'

housing The element l1 carries integrally a boss 26 Y which isinternally threaded and is located in spaced relation to the opening 25,with which it is in alignment. The boss 26is carried from the end wall23 of the element 11 by means of a semi-cylindrical neck 27 Whichprovides an open vsided chamber 28. The boss26 may be reinforced bymeans of a web 29 which entends` rearwardly from the element 11, boss 26and neck 27.V 9

A bolt 30 is threadedly mounted in theboss 26, said boltbeing providedat its outer end with ak head 31 whereby it maybe engaged projectitsinner endinto the chamber 28.

TheV improved wheel puller is particularly adapted for use withautomobile Wheels of'` known type in which the hub 32, Whichis rigidlymounted upon anaXle shaft 33, is provided vvith a kcircumferentialflange-'0r bead 84a short distance from the outer end of the hub. ItWill, however, be. understood that a suitable wrench and actuated s0 astov nut 18 and the bolt 8O is actuated so as to be moved inwardly andapply pressure to the end of the shaft 33. This actuation causes ak pullto be applied upon the housing Which is exerted through the flange 20around the Whole circumference of the iiange Si. lie engagement betweenthe edges of the .detent 21 `andthe recess 22, referred to above, com-`municates this pull from'the elem-ent 11 to the element 12 Vso that thissubstantially uniform 'distribution of the pull is obtained.

If desired, the inner end of the Vbolt may be provided with a conicalVpoint 35 which enters the center point in the end of the shaft andinsures alignment between the shaft 33 and the bolt 80. Approximatealignment is obtained by the engagement of the' shaft 33- With the'sidesof the opening 25 when the Wheel puller is applied to the Wheel.

Although the invention has been disclosecL in connection With thespecific details of preferred embodiments thereof, it must be understoodthat such details are not intended to belimi-tative of the invention,except insofar as set Aforth claims. y

l lVhat We claim as new and desire to secure by Letters Patent is:

' 1. A Wheel puller comprising a body portion Which includes a housingelement, a complementary housing element hinged thereto, saidelements inclosed condition providing a cup vshaped housing, a fiange at the mouthin the accompanying fend of each of said housing elements adapted toengage an annulus on Ythe hub of the Wheel around'itsV circumference,said elements at'their ends opposite the mouth ends 'being provided Withrecesses which register to provide an axial opening adapted to receivethe `Vend of the axle shaft, and means carried by one of the housingelements for applying axial -force to the axle shaft. Y A

2. A Wheel puller comprising two housing elements hinged together andadapted to vbe secured one to the other to form a cup shaped housing, aninwardly directed iange at the outer end of Yeach element, each of saidelements at its inner end being provided with a recess, said recessesbeing adapted to register toprovide'a central opening in the closedhousing, a b oss integral With one housing ele- 1nent,and 1n alignmentWith said opening, and a `bolt threadedlymounted in said boss.

3. `A Wheel puller comprising tvvo housing elements hinged together andadapted to ber secured one tothe other to form a cup shaped housing, aninwardly directed fiange at the outer end of each element, the innerends of said elements being provided With recesses which register toprovide a central opening in the closed housing, a .boss in alignmentwith said opening, a semi-cylindrical neck supporting same upon onehousing element, a rib reinforcing said boss and neck, and a boltthreadedly mounted in said boss.

' A Wheel puller comprising a body portion which includes a housingelement, a complementary housing element hinged thereto, said elementsin closed condition providing a cup shaped housing, a flange at themouth end of each of said housing elements adapted to engage an annuluson the hub of the Wheel around its circumference, said elements at theirends opposite the mouth ends being provided With recesses which registerto provide an'axial opening adapted to receive the end of the axleshaft, interengaging means carried on the meeting unhinged edges of thehousing elements, and means carried by one of the honsing elements forapplying axial force to the axle shaft.

nrwitness whereof. We hereunto subscribe our names this 24th day ofFebruary, 1931.
